    摘要： A particulate matter-sensing sensor assembly may include a housing in which an air flow passage through which air flowed thereinto from the outside thereof flows is formed, a fan motor internally disposed within the housing for flowing air into the air flow passage from the outside, a light source emitting light to allow light to intersect with air flowing into the air flow passage, and a light receiving sensor configured to receive light scattered by dust contained in air passing through the air flow passage, wherein the air flow passage is configured such that a region where air flows thereinto from the outside thereof has a cross-sectional area greater than that of a region where light emitted from the light source intersects with flowing air.
